Abstract

Conditions for lateral-shear interferogram formation in fringes of infinite width to control diverging wavefronts for a double-exposure recording of Fresnel holograms of a mat screen and Gabor's holograms of an amplitude scatterer are analyzed for the case of spatial filtering of a diffraction field in the record reproduction stage. Taking into account phase distortions of a higher-order approximation than the paraxial one is shown to limit the interferometer sensitivity where an off-axis reference wave is used.
